Aubrey de Grey is a biomedical gerontologist. He’s the co-founder and chief science officer of the SENS Research Foundation, which is a non-profit that does basic research on aging and treatments for aging. We start with the basics of aging, and some critical reactions to the notion that ageing could ever be overcome. Then Aubrey tells us about the seven types of damage that cause ageing and their corresponding repair technologies. I also ask him about the limits of model organisms in aging research. If at some point you’d like to skip to Aubrey talking about time estimates for ending aging and the effective altruism case for ending aging - you can skip approximately 1 hour and 34 minutes into the podcast.
